HTC EVO 4G :: Tingling Sensation In Right Index Finger When Touching Screen
Aug 23, 2010
I've noticed that I'm getting little tingling shocks to my right index finger whenever I touch the Evo's screen.What's even stranger is that I don't feel the sensation on any other fingers on either hand. Has anyone else had a similar experience with their evo screen and finger feeling little shocks?I'm not imagining this, and I'm wondering why the heck it's just my index finger?!? Maybe it's just more sensitive, but who knows.I would assume that the capacitive touchscreen technology is the culprit. I can live with the slight tingling, I just don't know why it's only on 1 finger!

I've had a screen protector on my HTC Desire since I got it (brilliant phone!). Two black vertical lines started to appear on the screen (only really visible when the background screen was white). So, I decided to take off the screen protector and risk scratching the screen.
However, without the screen protector, when I moved my finger on the screen I started getting a tingling sensation in my finger (a bit like that sensation when there's static around). I tried it for a few days and it's still the same. Has anyone else had this?
(This is the first capacitive touch screen I've had- I've only had Symbian UIQ touch phones in the past. I'm going back to having a screen protector which although not as smooth as the screen is at least comfortable to touch!)

Running my finger along the side of the case I noticed a weird sensation that at first I though was the finish on the casing, but it registered as more than that, so I unplugged it and it went away. Have since discovered that the sensation is only present when plugged in, but NOT charging - i.e. power light is green.

I want to create an event to change what my image button looks like, but only when it is being pushed down. So far I have been using an onTouch listener, but that just changes it permanently. I can't find anything like an onKyeUpListener() type of thing for the button.
Does anything like this exist? code...

anyone have this problem w/ the moment whereby your face touches the screen and causes accidentally pressed keys, things to move on screen, etc. associated w/ touching the screen? I think I remember this happening once or twice on the moment but admittedly, I don't use it much so not sure if the lock screen was on, screen was off, etc. Just looking to see if anyone if affected by this or if it's a known problem.

waiting for a swop out but just wondering if anyone has had a problem where the screen scrolls downwards of its own accord. Sometimes if on the browser, the screen will start going down the links. It's not just a browser thing either and can happen on any app or screen.It's an occasional thing. I've eliminated finger prints (put on a screen protector and it still happened), sunlight hitting the sensor (can happen indoors in the dark) and I've done a hard reset. It's driving me up the wall and I've been waiting 10 weeks for a replacement from T-mobile now (although the keep refunding me money so I can't complain too much).

My tablet has a problem that it usually (not always but most of the time) disables all sounds when I touch the screen. Depending on how long I touched the screen the sounds return immideadly or few seconds after I let go. When the sounds return it plays some of the sounds that should have played when I was touching the screen.
Android version is 4.1.1 and model number of the tablet is rk30sdk.

I own an HTC Hero and the phone can only be awaken by pressing the menu button or the power off button. Dunno if it's like this for every Android phone. I'm looking for a way to awake the phone by touching the screen. My idea is to replace the KeyGuard with something else but instead of awaking the phone by pressing one of those buttons, I would like to do it by touching the screen. Is this even possible or the Androd framework doesn't provide this functionality at all?

Try SpriteMethodTest, set 100 sprites, select OpenGL / Use VBO, let it run for a while. You will get something around 20ms / 50 fps. Now run it second time, and simply touch screen while test is running. You will get something around 35ms / 29 fps. So it is 15 ms difference. As I understand, the answer is simple - it is that dispatcher thread running with THREAD_PRIORITY_URGENT_DISPLAY priority.Setting THREAD_PRIORITY_URGENT_DISPLAY priority (will it work on non- ADP firmware?) on renderer thread yields 30 ms / 33 fps.

I want my application to resume what it is doing regardless of where I press the icon (Home screen, app picker, or running apps). Right now if my app is in the background and I press the icon on the home screen, the app restarts with my Main Activity. Once here, if I press the back button the app resumes from the activity it left off before it was put in the background. If it's running in the background and I hold the home button and select my app from the current running apps, it resumes correctly. How do I avoid my app from going to my Main activity when it is selected from the Home screen or app picker? I have tried adding the following in my Manifest XML file, but it doesn't help: <activity android:name=".Main" android:launchMode="singleTask" android:alwaysRetainTaskState="true" android: label= "@ string /app_name">

Is this possible? Many times my phone is in a holding frame of some kind (cars) and the button on the side isnt easily accessed. Is there an app or a way that a simple tap on the screen can activate the phone instead of requiring pushing the button on the side?

I understand calling onTouchEvent from views to get the location of the last touch as a motion event. How the heck can I tell that a figure is down on the screen and has not been lifted and when the finger is lifted?
For instance there is onKeyDown and onKeyUp for use when you are dealing with keyboard input. So how can I find out when on fingureUp happens?

My wifes Incredible started shifting the home screen to the right without any touching. When its centered the screen begins swiping to the right as if a finger was there. In "all programs" it starts highlighting apps as if I was touching them but I am not. I have tried G-sensor calibration, keyboard calibration, restarts and the closing of apps but cant find where the trouble lies. Is it possible the touchscreen is now defective?

I have a motion listener to detect finger down, finger drag, and finger up. I start my action at finger down and finish my action at finger up. When the action is finished, I store it in a stack for allowing undo. My problem is that if I don't get a finger up event, I can't finish my action to add it to the stack for undo.
How can I detect that the user's finger has left the screen?
I tried using the emulator to see if getEdgeFlags() ever returned anything useful, and the result was always 0.
Basically, if a finger leaves the screen, then nothing is touching the screen anymore and I would like to detect that as a finger up event. How can I do this?

I have rooted HTC sensation xe (Hboot 1.27, ICS 4.0.3, S-On). Tried installing custom ROMs. It installs but when I reboot from recovery, it gets stuck on home screen (white background with HTC). Tried Virtuous Inquisition and MIUI bit same problem.P.S. I am a rookie and read that it could be due to S-On even if rooted.

Anyone else notice when you're on a phone call if you move your finger near the little dot to the left of the verizon logo the screen will turn off? It's annoying when multitasking because that functionality remains regardless of whether the phone call is the active screen or not. If you are watching the Google Navigation screen and you're on a call, move your finger near the little dot next to the verizon logo and the screen turns off.

I have got one big problem with the touch input of my Hero. The screen is too sensitive. I can navigate on the screen while my finger is about 5 cm away from it. I can choose what I want, but the screen takes the right horizontal position of my finger, but not the vertical. Anything I want to take, the screen takes the one on the bottom of the screen. The same when I want to write a message or something like this. I choose the "W" or "E", but the screen takes the "X" or "C". If the display goes on Standby and I wake it again, everything is good for a few seconds, but than the same mistake comes again. I already tried to wipe and install a new MCR, but nothing helps. I think, but I am not sure, that I have that problem after I have installed the htc keyboard on android 2.1, as I tried it for a few hours.

I found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?

So I decided to upgrade the rom on my tmobile us sensation 4g and now it is stuck on the white screen with the green htc logo. Here are the steps that I took...
Download and run HTCSupertoolv3, run "root" option, run "attempt s-off and everything else" option - go through this process by getting key and submitting code to get update.bin file and then finish
Boot to recovery, phone says Unlocked at top
Download and run android recovery manager - flash clockworkmod5 on phone
Copy ordroid for sensation zip to sd card, boot to recovery, select zip file, go through installer - shows success
boot phone - white screen with htc logo
boot into recovery - wipe cache
white screen with htc logo, learn that I need latest firmware (3.3.2) for rom to work
copy pg58img.zip to sd card, do not modify file- boot into recovery, phone says parsing pg58img.zip - then nothing, no prompts or continue
boot phone - WHITE SCREEN WITH HTC LOGO

I would like to get access to the area covered by a finger for each touch event on an Android.Every touch event will result in a coordinate pair X and Y independent of how big the finger and consequently the touch area is that triggered the event. I was wondering if there is a way to get the area data which triggered the touch event e.g. size or coordinates NOT
